Sky Garden House by Guz Architects. Wierd, but I think it would be really nice to inhabit. It's also an interesting application of green roofs/roof gardens to a very modern, otherwise steel and concrete design.
House R is a contemporary family home located at the “Stadtgarten” (city park) in the centre of Karlsruhe, Germany by Christ Associated Architects. The house features a transparent facade that may be closed with a system of exterior shades for privacy.
